This invention relates to new and useful improvements in smoking pipes and has more particular reference to a pipe adapted to give a dry smoke.

More specifically, the invention contemplates characterizing the dry smoke pipe by the fact that it has a stem consisting of an inner section continuing into a right angle intermediate'section, which in turn continues into an outer section parallel to but displaced from the inner section.

Still further the invention contemplates the provision of an opening in the intermediate section arranged to permit the cleaning of the outer section.

Another one of the objects of this invention consists in the provision of a disc element or similar element adapted to close the opening mentioned in the previous paragraph and capable of being moved to a position in which the opening is unobstructed.

Still further the invention proposes the provision of a valve arranged in association with the disc element mentioned in the previous paragraph a element is opened, for the purposes hereinafter described.

For further comprehension of the invention, and of theobjects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the Various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. l is a perspective view of a pipe constructed according to this invention.

Fig. 2 is a longitudinal vertical view, partly in section, of the pipe shown in Fig. 1.

Fig. 3 is a bottom plan view of the pipe shown in Fig. 1.

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 2.

Fig. 5 is a fragmentary enlarged view of a portion of Fig. 2.

The dry smoke pipe, according to this invention, comprises a pipe bowl Ill which is provided with a stem portion comprising an inner section II continuing into an intermediate section 12, which in turn continues into an outer section l3 parallel to but offset from the inner section H. Preferably, the intermediate section I2 is arranged at right angles between the sections ll and I3.

The outer end of the section l3 comprises the mouthpiece for the pipe. A bore it extends through the sections and provides a passage for the smoke. An opening 15 is formed in the intermediate section it, in line with that section of the bore M which is formed in the outer sec tion l3. This opening [5 is normally closed with a disc element Hi.

The disc element 56 is mounted upon an arm ll which is pivotally mounted at its other end by a spindle E8. The spindle i8 passes through a support plate 19 to a hollow area 26 within the wall of the intermediate section. Within this hollow area there is a spring 2| which acts between the plate l8 and a head-22 formed upon the spindle 98. The spring 2| serves to force the disc element It against the end of the opening it; and furthermore holds the arm ii in the various rotated positions in which it may be placed. The arm is capable of being pivoted through as indicated by the dot and dash lines in Fig. 3, in which position the opening 15 is unobstructed.

It is possible to pass a pipe cleaner through the stem portion of the pipe and through the opening 5 for thoroughly cleaning the pipe. The disc element i6 may be moved into the closed position, or may be pivoted open as desired when the pipe is cleaned.

A butterfly valve 23 is fixedly mounted upon an extended portion I8 of the stem 18. This butterfly valve normally is in the open position when the disc l6 closes the opening l5. But when the disc I6 is moved so that thearm I1 is at right angles to its original position the butter fly valve 23 will have been turned through 90 to close the passage through the pipe stem. is then possible to blow through the stem portion so that the wind enters the mouthpiece end of the stem portion and discharges through the opening l5. This permits clearing out of foul air which may harbor within the passage Hi.

When the disc element I6 is closed upon the opening I 5 the butterfly valve 23 is turned into the open position. In the open position of the valve it is possible to pass a pipe cleaner past one side or the other side, thereof for cleaning the passage for the smoke.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the 0 right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:-

1. In a smoking pipe, a stem comprising an inner section continuing into an intermediate section, in turn continuing into an outer section, an opening in the intermediate section in line with the passage for the smoke through the outer section, and a member for closing said opening, comprising a disc element, mounted upon an arm pivotally mounted upon said intermediate section, a spindle pivotally supporting said arm, and a butterfly valve mounted upon the inner end of said spindle and being adapted to close the opening in the intermediate section when said valve is open.

2. In a smoking pipe, a stem comprising an inner section continuing into an intermediate section, in turn continuing into an outer section, an opening in the intermediate section in line with the passage for the smoke through the outer section, and a member for closing said opening, comprising a disc element, mounted upon an arm pivotally mounted upon said intermediate section, a spindle pivotally supporting said arm, and a butterfly valve mounted upon the inner end of said spindle and being adapted to close the opening in the intermediate section when said valve is open, said spindle engaging through a hollow within the intermediate section, and a spring coaxially mounted upon said spindle and acting between a stationary portion and a head element upon a portion of the spindle.

3. In a smoking pipe, a stem comprising an inner section continuing into an intermediate section, in turn continuing into an outer section, an opening in the intermediate section in line with the passage for the smoke through the outer section, and a member for closing said opening, comprising a disc element, mounted upon an arm pivotally mounted upon said intermediate section, said arm being fixed on a spindle en gaging into a hollow within the intermediate section, and a spring coaxially mounted upon said spindle and acting between a stationary portion and a head element upon a portion of the spindle, and a butterfly valve mounted upon an extended portion of said spindle for closing the passage through said stem when said arm is moved through 90.

4. In a smoking pipe, a stem comprising an inner section and an outer section parallel with each other but offset from each other, an inter mediate section connecting said inner section and said outer section and at right angles thereto and having an opening in line with the passage for smoke in the outer section, a disc element for normally closing said opening, a butterfly valve mounted in the passage for smoke in the intermediate section, and means connecting said disc element and said butterfly valve so that when said disc element is moved to open said opening said butterfly valve moves correspondingly to close the passage in said intermediate section.
